Hello Folks,
I have a really frustrating issue here which i am unable to solve.
So basically what is happening to my quadcopter right now is that the ESCs are taking turns to breakdown, this has happened over a timespan of 2 days, these ESCs had been working fine for about 3 weeks since i purchased them and flown with them, the problem only surfaced recently which is odd.
Day 1:
First flight of the day goes well, i land and swap a new pack of lipo, arm the pixhawk and attempt to spool up the motors, however now only 3 motors start spinning the other one starts jerking terribly.
I purchased a new ESC to replaced the faulty one and the problem is solved, the motor spools up perfectly.
Day 2.
First flight of the day again goes well, i land and again swap a new pack of lipo, arm the pixhawk and upon giving throttle, 3 motors spool up smoothly (yes including the previous one that was faulty), however the fourth one (which spooled up well on day 1) started jerking and afterwards completely stopped working.
I am totally clueless on what is going on, the ESCs just seem to be taking turns to break down.
Here is a video of what is happening during day 2:

My Quadcopter is equipped with the following electronics:
1 x Pixhawk
4 x T Motor MN3110-15 780KV
4 x Hobbyking 30A ESC flashed with the latest SimonK firmware
2 x MR APC 10 x 5.5 props
2 x MRP APC 10 x 5.5 props
1 x 4S Rhino 3700 Mah Lipo
*Just a quick note, i have tested the faulty ESCs with other motors and the same problem surfaces, i have also swap among the different channels on my pixhawk and the problem remains.
*I have also checked all the solder joints on the motors & ESC, and everything is good.

OK, so when you arm the quad, the motors start except one, but what hapens when you push the throttle just a little bit up? does the 4'th motor start?
I had the same problem on my F550 Hexacopter, and I solved it by calibrating the ESCs
Edit: Nevermind, looks like you solved your problem
